VENTILATING APPARATUS FOR BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 784,963, dated March14, 1905.

Application filed October 20, 1903. Serial No. 177,833.

To all wgwml it may concern.-

Be it known that 1, WILLIAM N. REYNOLDS, a citizen of the United States,residing at Pierre, in the county of Hughes and State of South Dakota,have invented a new and useful Ventilating Apparatus for Buildings, ofwhich the following is a specification.

This invention relates to ventilating apparatus for buildings; and itconsists, generally speaking, in means for supplying fresh air to theinterior of a building, and a ventilatingfiue comprising an inner fluefor the conduction of smoke and products of combustion from the buildingand an outer flue for the passage of foul air from within the building.

The object of the invention is to provide improved means for admittingfresh air into abuilding without causing disagreeable drafts and toprovide an improved form of flue for the conduction of foul air from thebuilding in such manner that the escaping foul air may increase theeiiiciency of the draft by which the fire in the heating apparatus issustained.

A further object of the invention is to improve the construction ofventilating-flues by reducing the cost of manufacture, increase thedurability of the fiues, and provide improved means for securingflue-sections in proper relative position, so preventing disarran gementof the flue-sections and consequent interference with the action of theflue.

In describing the invention reference will be had to the accompanyingdrawings, in which there is illustrated a preferred form of embodimentof the invention, it being understood, however, that various changes inthe form and proportions of the parts and in the exact mode ofassemblage thereof may be resorted to without departing from the spiritof the invention or sacrificing any of its advantages.

In the drawings, Figure 1 is a view in vertical section through the fineand through portions of the floor and ceiling of a room ventilatedthereby. Fig. 2 is a view in front elevation of the flue and theventilating-box. Fig. 3 is a view in section on the line 3 3 of Fig. 1looking in the direction indicated by the arrows. Fig. 4 is a view-insection on the line 44: of Fig. 1 looking in the direction indicated.upper section of the inner flue. Fig. 6 is a plan view of theventilating-box. showing portions of the air-inlet pipes leadingthereinto.

Referring to the drawings, in which corresponding parts are designatedby similar characters of reference, F designates a floor in abuilding,which for the sake of simplicity is shown as being of one storyonly. In the floor Fthere is located a box I, which may be of anysuitable contour and which has arranged in the sides thereof near thebottom pipes 2, which extend from the outside of the building into thebox and convey fresh air thereinto. In the top of the box, which will bemade flush with the upper surface of the floor, there is arranged aregister comprising, preferably, a rotatable disk 3, having a pluralityof openings 4 of the same contour as openings 5, correspondingly spacedin the top of the box. A disk 3 is pivotally supported upon the top ofthe box and is provided with a knob or handle 6 for imparting movementthereto. The movement of the disk is preferably limited by means of aslot 7 at the periphery of the disk and stud 8 upon the top of the box.The box 1 will preferably belocated in the floor immediately beneath theheating apparatus, which in this instance is a stove 9 of any suitablecharacter, the object of this arrangement being to insure the heating ofthe air as it enters the building and the prevention of its gradualdiffusion throughout the room by deflection in all directions from thebottom of the stove, thereby to prevent the creation of disagreeabledrafts,which are not only productive of discomfort to persons within thebuilding, but are also apt to lead to colds and other forms of illness.

The flue is illustrated as consisting of three outer sections 11, 12,and 13 and three inner sections 14, 15, and 16; but it is to beunderstood that the number of sections will be in all cases determinedby the height of the building and the character of the sections employedwill Fig. 5 is a perspective view of the depend upon the number ofstories to be reached. The bottom section 11 of the flue is closed atthe bottom, as shown, by means of a plate or partition 17, upon theupper surface of which are arranged two bars 18, cut away on their uppersurfaces to form seats 19 for the lower section 1% of the inner flue,which is prevented from moving laterally upon the seats by blocks 20,located adjacent to the bars 17 and adapted to contact with the sides ofthe inner-flue section. Lateral movement of the upper portion of theinner-flue sections will be prevented by cleats 21, fixed on the insideof the outer-flue section and presenting down wardly-inclined uppersurfaces to facilitate the guidance of the inner flue into position, andsimilar cleats 22, fixed in the reverse position upon the inner-fluesection. The fluesection 11, is provided near the bottom, at a slightdistance only above the floor, with a pair of registers 23, similar tothat already described upon the upper surface of the box 1, and hencerequiring no further and more detailed description. The outer-fluesection 12, which in this instance is shown as extending to the top ofthe room, is provided on the inside with cleats 21, similar to those onthe fluesection 11, and is provided near the top with a pair ofregisters 24, similar to those employed on the lower-flue section. Thefluescction is also provided with an opening 25 to receive a stovepipe26, this opening being located between the registers 24: and at aboutthe level of their lower margins.

The upper-flue section 13 is provided at the top with inwardlydisposedflanges 27 to form guides for the inner-flue section 16, which isprovided at the top with a broad flange 28, which is adapted torest uponthe top of the outer flue and form a close joint therewith. Theinner-flue section 16 is also provided on opposite sides withhorizontallydisposed apertures 29, forming means of communication withthe space between the outer and inner flues, so that the foul air whichwill pass upward into the space between the outer and inner flues maypass into the inner flue before its final passage into the open air andby so doing increase the draft of the inner fine and at the same timeextinguish sparks which may rise to the top of the inner flue.

Both the inner and outer flue sections are arranged to interlock, asshown, the flue-sections 11, 12, 14, and 15 being provided at the topwith an external rabbet and flue-sections '12, 13, 15, and 16 being eachprovided at the lower end with an internal rabbet, so that theflue-sections may be interlocked, as shown. The sections of the outerflue are also pro vided with inwardly-disposed lugs 30 at the corners,which have openings to receive rods 31, which extend from top to bottomof the flue and are threaded at one end to receive nuts 32 and areprovided at the other end with heads 33. The rods 31 are, in effect,bolts extending throughout the entire length of the fine and "form meansfor positively preventing the loosening or disarrangement even in theslightest degree of the flue-sections. To facilitate the cleaning of theinner flue, openings 3 1 and are formed in the inner and outer flues,respectively, and are covered by pivoted closures 36 and 37 Thestovepipe 26 is of course extended through the inner-flue Wall as wellas through the outer fine, and the smoke and other products ofcombustion from the stovepass directly from the stove into the innerflue, to be carried upward in the usual manner.

The registers 23 are disposed near the floor in order that the heavyfoul air and any noxious vapors heavier than air may pass readily intothe outer flue at that point, and the registers 24 are arranged near thetop of the room, so that the heated air, which rises on account of itslightness, may find egress from the room. The escaping foul air whichpasses outward through the outer flue will pass into the inner fine atthe top through the openings 29 and by so doing will have the doubleeffect of increasing the efficiency of the draft through the inner flueand also by deflecting sparks against the side walls of the flue tend toextinguish them before escape into the outer air. By means of theregisters in the box 1 and in the outer flue the entrance of fresh airand the escape of foul air may be easily regulated to meet therequirements within a building at any time and proper action of thedraft in the flue and a supply of fresh air conveniently and easilycontrolled.

In the construction of the flue any suitable material may be employed;but that which is to be preferred on account of its lightness inproportion to its strength and its durability in service is iron, and bycasting the fluesections they may be made at comparatively low cost.

Having thus described the construction and operation of my invention,what I claim as new, and desire to secure by Letters Patent, is

The combination in apparatus of the class described, of an outer fluehaving openings near the floor and the ceiling of the room in which theflue is located for foul air to pass into the flue and an intermediateopening, an inner flue having an opening interl'nediate of its endsregistering with the intermediate opening in the outerflue, a heatingapparatus spaced apart from the outer flue, means for admitting cold airbelow said heating apparatus and for controlling the entry thereof,means for conveying products of combustion from the heating apparatusthrough the registering openings to the inner flue, the latter my own Ihave hereto affixed my signature in beingprovided at the top thereofWith openthe presence of'two Witnesses. ings communicating with thespace between J -T i the inner and outer flues and With an out- ILLIAMREXLOLDb' 5 wardly-disposed flange forming a closure for WVitnesses:
